[PATCH] scsi: qla2xxx: check for kstrtol() failure

[Dan Carpenter]

The error handling was unintentionally left out so it introduces a
Smatch static checker warning:

    drivers/scsi/qla2xxx/qla_attr.c:1655 qla2x00_port_speed_store()
    error: uninitialized symbol 'type'.

Fixes: a7b9ca7fc87a ("scsi: qla2xxx: Add support for setting port speed")
